How to tweak memory for Grails using Heroku and Searchable

How to tweak memory for Grails using Heroku and Searchable - grails

I'm using Grails 2.3.7 on Heroku and the searchable plugin. I have 2 nodes of 512Mb RAM. My app was fine on Grails 2.3.5 but now not so much on Grails 2.3.7. Since I've updated I've noticed a 10-30% memory jump (before I was around running at 100% to 102%, now I'm 116% to 130%). So I started doing some tweaking, taking out plugins..etc. to try and bring the memory usage back down.
One thing I noticed in my logs is that the searchable index fails to build now:

Looks like it runs out of heap space. This brings me to ask you all, what is the optimal way to tweak the searchable plugin or grails for Heroku without jumping to 2 x 1Gb nodes?

install4j: Could not load config file /opt/atlassian/pipelines/agent/build/_installer/_install....
I'm using debian:jessie as a base image. Running tests and creating the JAR works, but I'm stuck creating the installer. How can I solve this? Is what I'm trying to do possible (create windows installer inside a docker)?
I've tried to enable all the debug info in the gradle task not sure what I could try to get this running.
I also need to know will a project I setup with the gui in windows work in a linux environment?

Install4j initializes the AWT even in headless mode and the AWT needs certain font libraries to be installed. Installing the libfontconfig1-dev package by executing
apt-get install -y libfontconfig1-dev
will fix this issue.

Is it possible to string interpolate the input for a cron trigger in a pipeline Jenkinsfile?

I'm trying to do the following:
pipeline {
agent none
parameters {
string(name: 'PARAM_1', defaultValue: '0 5 * * *', description: 'cron value for PARAM_1')
string(name: 'PARAM_2', defaultValue: '0 9 * * 4', description: 'cron value for PARAM_2')
}
triggers {
cron("${params.PARAM_1} \n ${params.PARAM_2}")
}
...
// Do additional logic with parameters in stage
}
When I do the above, I get the following error:
line 1:1: unexpected char: 'n'

I am not sure what I am doing wrong. I thought you can do string interpolation with double quotes in the Jenkinsfile/Groovy. Are the parameters just not defined until after the triggers hit? Is there a better way of doing what I am trying to do?

I was able to achieve this in a different manner:
def PARAM_1 = '0 5 * * *'
def PARAM_2 = '0 9 * * 4'
pipeline {
agent none
triggers {
cron("${PARAM_1} \n ${PARAM_2}")
}
...
// Do additional logic with parameters in stage
}

Strange 'Unknown Property' error in grails

i've just been giving grails a go, followed the most basic tutorial and that worked, but then moved onto the next most basic, where I create one class which has a many to one relationship to another.
say we have a class Trip which has a field airline of type Airline. the classes both have a few other fields, but they are just primitives.
now, if I create a Trip object and set the airline field to and new instance of Airline that code executes normally. but if I try execute (which i did by putting the following in grails-app/conf/Bootstrap.groovy:
Trip t = new Trip (...)
t.airline = new Airline(...)
println t.airline
it gives a huge error with a massive stack trace.
org.springframework.beans.factory.access.BootstrapException: Error executing bootstraps; nested exception is org.codehaus.groovy.runtime.InvokerInvocationException: java.lang.NoSuchMethodException: Unknown property 'airline'

Looks like your Trip class doesn't have an "airline" property.
If I have the following classes, it works fine:
// grails-app/domain/Trip.groovy
class Trip {
String name
static belongsTo = [airline: Airline]
String toString() { name }
}
// grails-app/domain/Airline.groovy
class Airline {
String name
static hasMany = [trips: Trip]
String toString() { name }
}
Then open up "grails console" and run this code:
Trip t = new Trip(name: "my trip")
t.airline = new Airline(name: "Delta")
assert "Delta" == t.airline.name
Check out the One-to-many grails docs for more info.
